SPECIFICATION forming part of Letters Patent No. 625,194, dated May 16, 1899. Application filed September 19, 1898 Serial No. 691,287. (No model.)

T0 at whom it may concern:

Be it known that I, FRANK PARKER, a subject of Victoria, Queen of the United Kingdom of Great Britain and Ireland, and a resident of Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Bobbins for Spinning, Twisting, and W'inding, of which the following is a specification.

My invention relates to bobbins for spinning, twisting, and winding. Many such bobbins instead of being fitted closely to the spindle and being driven by adhesive contact therewith surround the spindle loosely and rest upon a flange or disk concentric with the spindle and rigidly secured thereto, each such flange or disk being provided with one or more upward projections, which enter an annular or circular recess in the head of a bobbin and engage a pin or pins driven into said head within said recess parallel with the axis of the bobbin. In such a bobbin it frequently happens that the shrinkage of the bobbin, which is commonly made of wood, with the grain running lengthwise of the bobbin, causes the head to split at the pin radially, loosening the pin and allowing the same to fall out, or the pin sometimes becomes loose by the expansion and contraction of the wood without the wood splitting.

The object of this invention is partly to prevent the bobbin from splitting, but mainly to prevent the pin from falling out of place- This object I accomplish by a guard or shield attached to the head of the bobbin and overlying the outer end of the pin in such a manner as to render it impossible for the pin to be withdrawn or fall out while said guard remains intact.

In the accompanying drawings, Figure 1 is anisometric perspective 'view of a bobbin provided with my improvement; Fig. 2, a central longitudinal section of the headof said improved bobbin on the line 2 2 in Fig. 3 or Fig. 5; Fig. 3, a reverse plan of the same; Fig. 4., a similar View of the inner face of the guard or shield detached; Fig. 5, a plan of a bobbin-head with three pins; Fig. 6-, a plan of the inner face of a guard or shield adapted to cover the head and pins shown in Fig. 5.

The bobbin A, consisting of the barrel a and head a, is of a common construction of filling bobbins, except as hereinafter stated,

the head (1 having a nearly conical shape,

shuttle, and thereby to be retained on the" shuttle-spindle in the usual manner.

The bobbin A is provided with the usual central longitudinal opening a to receive a spinningspindle or a shuttle spindle or skewer. The end of the opening a has a cylindrical enlargement a within or partly within which and partly in the surrounding part of the head is driven one or more pins B (one such pin being shown in Fig. 3 and three such pins being shown in Fig. 5) to be engaged by projections carried by a disk on the spinning-spindle in the usual manner and as above stated.

To prevent the pin B from being loosened by the shrinking and expansion of, the head (due sometimes to natural variation of the atmosphere and sometimes to steaming and drying the yarn while on the bobbins) or by the splitting of the head at the pins, I apply the guard or shield O to the head a. The shield Oconsists of a metallic ferrule or ring 0, preferably of sheet metal, as sheet-brass, adapted to surround and fit the head ct and having an inwardly-extending flange c to rest upon the end of said head, said flange having an inward projection 0 and said flange c and projection 0 having a sufficient width to cover the annular portion a, of the end of said head (around the recess or cylindrical enlargement a and the end of the pin 13 and to be turned down at its inner edge at 0 within said recess. In practice the shield C may be formed with dies at one operation, with the ferrule o, flange 0, projection 0 and turned edge 0 asshown in Figs. 3 and 6, ready to be placed onthe bobbin-head. Turning down the edge at c prevents said edge from catching yarns or. lint and stifiens the shield. After the shield is placed on the head the edge 0 of the ring or. ferrule c is spun into the annular groove above mentioned and prevents the shield from falling off the head or being drawn therefrom by being caught on the bobbin-catch of the shuttle or other ob ject. The guard C also tends to prevent the bobbin from being broken by being stepped on or by other weight resting thereon.

I claim as my invention- 1. The combination of a bobbin, having a head provided with a recess in the end thereof, a pin, arranged in said head and partly Within said recess and a shield or guard, secured to said head and covering the end of said head outside of said recess and extending over the outer end of said pin.

2. The combination of a bobbin, having a head provided with a recess in the end thereof, a pin, arranged in said head and partly within said recess and a shield or guard, secured to said head and covering the end of said head outside of said recess and extending over the outer end of said pin, the inner edge of said guard or shield being bent into said recess.

3. The combination of a bobbin, having a head, provided with an annular groove around the same and with a recess in the outer end thereof, a pin, arranged in said head partly within said recess, and a shield or guard, consisting of a ferrule or ring which surrounds said head and has at one end an internal flange which covers said end of said head and the outer end of pin and is bent into said recess, the other end of said ferrule or ring being bent into said annular groove, to retain said guard or shield on said head.

In testimony whereof I have affixed my signature in presence of two Witnesses.

FRANK PARKER.
